According to one embodiment, an electronic device 400 may be a portableelectronic device such as a smart phone. The electronic device 400 canoperate in various operating modes (also called operating states), andthe operating modes may include a wakeup mode, in which the processor(e.g., application processor) provides various functions and providesvarious images on the display in support of those functions. Theoperating modes may also include a sleep mode in which the display maybe turned off and the processor waits for a user input.

FIG. 4(a) illustrates an always on display (AOD) screen 410. Accordingto one embodiment, the AOD function is performed by the electronicdevice 400 during its sleep mode.

In the sleep mode, at least one hardware module or software moduleincluded in the electronic device 400 may be deactivated, such thatminimum power may be supplied to the components of the electronic deviceto perform only a predetermined function required in the sleep mode. Forexample, if the electronic device's camera module is switched to thesleep mode, photo and video functions are deactivated. If the processoris switched to the sleep mode, the processing functions of the processormay be limited. Accordingly, during the sleep mode, various functions ofthe electronic device's hardware modules and/or software modules may bedeactivated such that the device's battery life increases.

With the AOD function, the electronic device displays information, suchas important information, all the time, regardless of whether it is insleep mode. To implement AOD, the electronic device may employ low powerduring the sleep mode. For example, the electronic device 400 candisplay information such as clock, calendar, weather, remaining battery,missed call, new text message, etc. in the AOD screen 410 in a partialarea of a display. In one embodiment, the user may select the desiredinformation to be displayed by entering a user input, such as a swipegesture in the partial area.

Here, the screen switching event may includean event triggered by a user operation such as a touch input, key input,and tilt input for a touch screen. In addition, the screen switchingevent may include an interrupt event caused by various events such asreception of a short message service (SMS) message or E-mail, a pushmessage reception, call reception, etc.

In the wakeup mode, various hardware modules and/or software modules(e.g., each component of electronic device 101 of FIG. 1 and/orelectronic device 201 of FIG. 2) included in the electronic device 400receive sufficient power from the battery so that they perform theirintended functions. For example, in the wakeup mode, the display canexpress various contents, and the processor can provide variousfunctions of the electronic device 400.

The user can also switch from the lock screen 420 to the home screen430. When the lock screen 420 is displayed and a specific screenswitching event (e.g., touch input, password input, and lock patterninput) is generated, the lock screen 420 can be switched to the homescreen 430.

According to one embodiment, the AOD screen 410, lock screen 420, andhome screen 430 can be generated individually by different applications.Hereinafter, an application generating the AOD screen 410 is called thefirst application, an application displaying the lock screen 420 iscalled the second application, and an application displaying the homescreen 430 is called the third application. According to an embodiment,the first application can be executed by a first processor (e.g.,display driver IC) capable of being driven in the low-power or sleepmode, and the second application and the third application can beexecuted by a second processor (e.g., application processor).

According to one embodiment, at least one object may be displayed on theAOD screen 410 while switching to the lock screen 420 or the home screen430. The at least one object can provide a cinematic effect bydynamically moving during the switching of the various screens.

Here, thesecond application may be an application for generating a screen (e.g.,lock screen 420 of FIG. 4 or home screen 430 of FIG. 4) that isdisplayed after screen switching. Hereinafter, it is assumed that thesecond screen switched from the first screen (e.g., AOD screen) is thelock screen.

According to one embodiment, at least one object displayed in the firstscreen and the second screen can move continuously. Namely, theelectronic device 500 can provide a dynamically changing backgroundscreen. The attribute information is used for providing the currentinformation (e.g. location and size) of the at least one object to thesecond application, so that the at least one object can be displayedcontinuously in the second screen. In addition, the attributeinformation may include information related to locations of otherobjects such as the icons and widgets displayed in the first screen.Further, according to an embodiment, the processor can provide for thesecond application information related to objects (e.g., icon andwidget) not being displayed in the second screen among at least oneobject being displayed in the first screen.

The second application 662 and thethird application 663 may be executed by a second processor (e.g.,second processor 514 of FIG. 5).

If a screen switching event is detected while the first screen (e.g.,AOD screen) is displayed, the first application 661 can provideattribute information of at least one object included in the firstscreen to the framework 670, and the framework 670 can identify thesecond application 662 and provide the attribute information to thesecond application 662.

The second application 662 can generate the second screen (e.g., lockscreen) based on the attribute information, and object may be displayedseamlessly when transitioning from the first screen to the secondscreen.

If a screen switching event is detected while displaying the secondscreen, the second application 662 can provide attribute information ofthe object included in the second screen to the framework 670, and theframework 670 can identify the third application 663 and provide theattribute information to the third application 663.

The third application 663 can generate the third screen (e.g., lockscreen) based on the attribute information, and objects may be displayedseamlessly when transitioning from the second screen to the thirdscreen.

Similarly, a screen switching event for switching to the first screen orthe second screen may occur while displaying the third screen. In thiscase, the third application 663 can provide attribute information of theobject to the framework 670, and the framework 670 can identify anapplication for generating the screen after the screen switching eventand provide the attribute information to the corresponding application.

Subsequently, the objects may move from the third location1030 back to the second location 1020 and the first location 1010.

If a screen switching event is generated when the object is at the firstlocation 1010 and when the first screen is displayed, the firstapplication can provide attribute information (e.g., coordinateinformation) of the object to the second application. The secondapplication can generate a second screen based on the attributeinformation, and the object may be initially displayed at the firstlocation 1010 and move continuously to the second location 1020 when thesecond screen is displayed.
